Description

The Blom-Singer Advantage Indwelling Voice Prosthesis, developed by InHealth Technologies, is a specialized medical device designed for individuals who have undergone a total laryngectomy. This prosthesis plays a crucial role in voice rehabilitation by facilitating speech through a tracheoesophageal puncture (TEP), a surgically created connection between the trachea and esophagus.

Key Features

• One-Way Valve: The device features a one-way silicone valve embedded with silver oxide, which helps preserve the material and may reduce the need for anti-fungal agents. This valve allows air to pass from the lungs to the esophagus, enabling voice production while preventing food and liquids from entering the trachea.

• Retention Flange: Equipped with an easy-fold esophageal retention flange, the prosthesis is designed for secure placement. The flange introducer aids in the insertion process, making it less traumatic for the patient.

• Insertion System: The Blom-Singer Gel Cap Insertion System ensures atraumatic insertion, making the procedure smoother for healthcare professionals.

Cleaning and Maintenance

The device includes a Brush and Flush Cleaning System, complete with built-in safety features, to maintain hygiene and functionality. Proper cleaning is essential and typically managed by healthcare professionals who provide training and support for patients.

Sizing and Kit Contents

Available in two diameters (16 French and 20 French) and various lengths ranging from 4 mm to 22 mm, the prosthesis offers flexibility to meet individual patient needs. Each package comes with a secondary placement kit, including an inserter, flange introducer, gel caps, and lubricant.

Intended Use

This indwelling voice prosthesis is particularly suitable for patients who are unable or resistant to changing a removable device. It is exclusively inserted and replaced by a speech-language pathologist or physician, ensuring professional management.

Additional Accessories

The Blom-Singer Plug Insert, available in 16 Fr. and 20 Fr., can be used temporarily to prevent leakage, though it is not intended for voicing.

Device Lifespan

The lifespan of the device varies, with a reported mean lifespan of approximately 97 days. Leakage is the most common reason for device replacement, and some versions are designed for increased durability and airflow resistance.

Innovation and History

Introduced in 2003, the Blom-Singer Advantage was the first to incorporate silver oxide in its valve design, marking a significant advancement in material preservation. Some sizes may be available by special order, catering to specific patient requirements.
